Objectives : Atopic dermatitis is a chronic inflammatory skin disease with frequent relapses. This study was to investigate the effects of Gammakdaejo-tang(GMD) in DNCB induced atopic dermatitis mice. Methods : The study was divided into five comparion groups. 2,4-dinitrochlorobenzene(DNCB) solution was applied to Nc/Nga mice to induce atopic dermatitis, followed by normal group, negative control group with distilled water, positive control group with Dexamethasione and GMD 200mg/kg or 400mg/kg. The control group was orally administered 200㎕ once daily for 4 weeks. Visual skin condition, Immunoglobulin E, Histamine, Cytokine, Immune cells, Tissue biomarkers were observed. Results : As a result of the dermatitis score evaluation, it was confirmed that the GMD-administered group improved symptoms compared to the negative control group. As a result of measuring IgE, the GMD-administered group significantly decreased compared to the negative control group. As a result of measuring Histamine, GMD group except 200mg/kg of GMD significantly decreased compared to negative control group. As a result of measuring cytokine, GMD 200mg/kg significantly reduced IL-1β, IL-6 and TNF-α compared to the negative control. 400mg/kg significantly reduced IL-1β, IL-4, IL-5, IL-6, IL-10, TNF-α and significantly increased IL-2, IFNγ. As a result of confirming the immune cells, all experimental groups showed no difference in basophil, GMD group significantly reduced monocyte and eosinophil compared to negative control group, and GMD 400mg/kg group significantly reduced white blood cell and neutrophil. And significantly increased lymphocytes. As a result of measuring the gene expression level, all GMD group significantly increased TGF-β1 compared with the negative control group, and filaggrin, VEGF and EGF were significantly increased in GMD 400mg/kg group. Epidermis, dermis thickness, and eosinophil infiltration were found to be decreased in all GMD groups compared with the negative control group. Conclusions : GMD is effective in atopic dermatitis by reducing imbalance of immune response of T cells (Th1 / Th2) and reducing skin tissue damage and inflammatory response.

Background : Priming and boosting vaccination strategy has been widely explored for new vaccine development against tuberculosis. As an effort to identify other vaccine candidates, this study was initiated to evaluate protective efficacy of adenylate kinase (AK), nucleoside diphosphate kinase (NdK), and heat shock protein 70 (Hsp70) of Mycobacterium tuberculosis. Method : M. tuberculosis genes encoding AK, NdK, and Hsp70 proteins were amplified by PCR and cloned into E. coli expression vector, pQE30. Recombinant AK, NdK, and Hsp70 was purified through Ni-NTA resin. To evaluate immune responses, we performed enzyme-linked immunosorbent assay (ELISA) for IgG isotype and $IFN-{\gamma}$ after mice were immunized subcutaneously with recombinant proteins delivered in dimethyl dioctadecylammonium bromide (DDA). Immunized- and control groups were challenged by aerosol with M. tuberculosis. The spleens and lungs of mice were removed aseptically and cultured for CFU of M. tuberculosis. Result : Vaccination with recombinant proteins AK, NdK, and Hsp70 delivered in DDA elicited significant level of antibody and $IFN-{\gamma}$ responses to corresponding antigens but no protective immunity comparable to that achieved with Mycobacterium bovis BCG. Conclusion : Recombinant proteins AK, NdK, and Hsp70 do not effectively control growth of M. tuberculosis in mice when immunized with DDA as an adjuvant.

Groundwater level drawdown of the first stage resulted from groundwater leakage into tunnel was predicted by an analytical approximation. And numerical modeling was performed to predict the flow rates into tunnel and the groundwater level decline in the vicinity of future proposed tunnel area using a groundwater flow model MODFLOW. Groundwater level of the first stage was predicted to decrease by 15.3 m in analytical approximation. The flow rates in the total length of the future tunnel, when it is excavated, would be approximately $1,870m^3/day$ in numerical model. The model predicts that the groundwater levels in the area around the future tunnel are expected to drop between 5 to 25 m relative to current groundwater levels. Under condition for a $50\%$ tunnel conductance increase, the flow rate was estimated to be $2,518m^3/day$ and the groundwater level drawdown was predicted to be between 5 to 35 m The flow rate and the predicted groundwater level drawdown under a $2,518m^3/day$ tunnel conductance decrease was estimated to be $1,273m^3/day$ and between 2 to 12 m.

Objectives : The aim of this study was to investigate the asthma-suppressive and immuno-regulatory effect of Lepidii Semen Herbal-acupu ncture(LS-HA) at $Joksanmi(ST_{36})$ on ovalbumin(OVA)-induced asthma in mice. Methods : C57BL/6 mice out of all the experimental groups, except the Normal group and the LS-HA group, were sensitized and challenged with OVA. The mice in the LS-HA group and the OVA-LS-HA group were treated with LS-HA(1%) at $Joksanmi(ST_{36})$. The mice in the OVA-Saline group were injected with saline at $Joksanmi(ST_{36})$. The mice in the OVA-Needle-Prick group were treated with a single prick with an injection needle at $Joksanmi(ST_{36})$. LS-HA, saline injection and needle prick were administered for 8 weeks, three times a week. Results : The lung weight and total cells in lung of the OVA-LS-HA group decreased significantly compared with those of the OVA-Control group. Total leukocytes and eosinophils in BALF of the OVA-LS-HA group decreased significantly compared with those of the OVA-Control group. The collagen accumulation in the lung sections of the OVA-LS-HA group decreased significantly compared with that of the OVA-control group. The concentrations of IL-4, IL-5, IL-13, IgE in BALF and serum of the OVA-LS-HA group decreased significantly compared with those of the OVA-Control group. The numbers of $Gr-1^+/CD11b^+$, $CCR3^+$, $CD3e^+$, $CD19^+$, $CD3e^+/CD69^+$cells in the OVA-LS-HA group decreased significantly compared with those of the OVA-Control group. The mRNA expressions of $TNF-{\alpha}$, IL-5, IL-4 and IL-13 in lung of the OVA-LS-HA group decreased significantly compared with those of the OVA-Control group. Conclusions: These results suggest that LS-HA at $Joksamni(ST_{36})$ is considered to be effective in treating asthma and to be put to practical use in the future asthma clinic.

A paragonimiasis infestation is caused by the paragonimus species. It is commonly found in the lung but has also been found to exist extrapulmonary infestations including cerebral, spinal, subcutaneous, hepatic, splenic, abdominal, urinary, and gynecologic infestation. On the other hand, a cutaneous infestation is extremely rare. Human infestation is caused by ingesting raw or undercooked intermediate hosts. Because paragonimus westermani larva mature to an adult worm in the lung, the possibility of identifying the adult worm of paragonimus westermani at extrapulmonary region is very rare. Case : After ingesting a fresh-water crab 1 month prior to the hospital visit, a 45-year old female patient was suffering from right pleuritic chest pain during that 1 month. The patient also complained of a palpable mass that was movable and migrating, and it was localized at the right upper quadrant of the abdomen. The eosinophil fraction of the white blood cell of peripheral blood and pleural fluid was elevated to 55.1% and 90%, respectively. Parasite eggs were not found in her sputum and stool examination. By using the enzyme-linked immunosorbent assay (ELISA), the paragonimus-specific IgG antibody titer was elevated to 0.28. During incisional biopsy, we were able to find the young adult worm of paragonimus westermani. We experienced the rare case of ectopic paragonimiasis with pleural effusion that was confirmed by identifying the adult worm of paragonimus westermani within the abdominal subcutaneous tissue. We report a case with brief literature reviews.

Objectives: The purposes of this study were to determine the relationship between the prevalence of allergic diseases and urinary cadmium concentration among children from six to 12 years of age, and to evaluate the association between cadmium in urine and other immunologically related factors in two elementary schools with different environmental conditions. Methods: Data on physician-diagnosed prevalence over the past 12 months and potential risk factors for allergic disease were collected from survey results drawn from 236 children living in different regions (central urban vs. suburban) from April to July in 2014 by an ISAAC questionnaire. We analyzed cytokine levels in serum through enzyme-linked immunosorbent assay and urinary cadmium concentration by use of inductively coupled plasma mass spectrometry. Results: Concentrations of urinary cadmium in suburban and central urban children were $0.11{\pm}0.11ug/L$, $0.14{\pm}0.17ug/L$, respectively (p>0.05). Results from the analysis of the t-test and chi-square test showed that urinary cadmium levels were positively associated with environmental factors (paternal smoking status, passive smoking, traffic volume and experiences of outdoor odors) and individual genetic factors (parental allergic disease). Cadmium concentrations in urine were also positively associated with the prevalence of allergic disease and immune-related cytokines (eosinophils, IgE, IL-5, IL-33, IL-17). Conclusion: This study suggests that genetic factors (parental history of allergic diseases), environmental factors, and regional status (suburban and central urban) should be considered as probable factors increasing the concentration of urinary cadmium, which has the potential to influence the allergic disease prevalence of school-age children.

This experiment was conducted on 60 Hanwoo calves comprising five feed additive groups, with 12 calves in each group, to determine the effects of additives at pre- and post-weaning on growth performance and blood profile. The groups were control, antibiotic (Neomycin 110 ppm), illite (2%), fermented green tea probiotics (FGTP, 0.5%), and mixed additives (FGTP 0.25%, illite 1% and licorice 0.1%). The calves were offered experimental pellet feeds ad libitum and after one month were supplied with imported timothy hay. They moved freely within the group and suckled their mother' milk during the pre-weaning stage (birth to 3 months) and were separated from their dam during the post-weaning stage (4-5 months). During the pre-weaning stage, the highest average daily gain (ADG) was recorded in the antibiotic- and mixed additive-fed groups followed by FGTP, control and illite groups. In the post-weaning stage, significantly higher total weight gain and ADG were recorded in both the FGTP and mixed additive groups compared to the other groups (p<0.05). Feed efficiency of mixed additive- and illite-fed calves were almost similar with antibiotic-fed calves compared to the other two groups, but the ADG was lowest in illite-fed calves during the pre-weaning stage. In contrast, post-weaning calves fed FGTP and mixed additives showed better feed efficiency. The values of hematological indices, differential leukocyte count, blood proteins and immunoglobulin among the additive-fed calves were not significantly different (p>0.05), although hemoglobin and hematocrit values were lower in FGTP compared to control, but similar in mixed additive and antibiotic groups. These results indicate no detrimental effects of feed additives on the blood profile of calves at both pre- and post-weaning age. Serum albumin in post-weaning calves of all feed additive groups were similar but significantly lower (p<0.05) than in the control group. Post-weaning, IgM was significantly lower (p<0.05) in illite-fed calves compared to other treatment groups, but there was no difference at pre-weaning. Considering all factors, the mixed feed additives and FGTP can be the replacement feed formula for antibiotic for Hanwoo beef calf production, especially when used post- weaning.

A previous study suggested that the phyto-extract mixture (PEM381) containing Camellia sinensis (leaf), Psidium guajava (leaf), and Rosa hybrida (flower) inhibited not only arachidonic acid cascade-related enzymes (5-lipoxygenase and cyclooxygenase) in vitro but also degranulation and histamine release from rat peritoneal mast cells. In this study, the same PEM381 was used to investigate its inhibitory effects on the syntheses of leukotrienes and prostaglandins as well as on serum concentration of histamine and eosinophils infiltration in type I allergic reaction-induced mice. The PEM381 could decrease concentrations of serum cysteinyl leukotrienes from mice activated by anti-DNP IgE and DNP-albumin. The concentration of serum histamine by oral administration of PEM381 (25, 50, and 100 mg/kg of body weight) in type I allergic reaction-induced mice was $395.93{\pm}190.37$ nM, $315.59{\pm}164.23$ nM, and $325.07{\pm}112.02$ nM, respectively, while that of positive control (promethazine hydrochloride 10 mg/kg of body weight) was $270.12{\pm}24.02$ nM. In addition, the PEM381 also showed inhibitory effect on the eosinophils infiltration in the nasal mucosa of mice which were sensitized with ovalbumin. However, the effect of PEM381 on the syntheses of prostaglandins seemed to be insignificant. Consequently, these results suggest that PEM381 may be useful for the prevention and treatment of type I allergy-related diseases.
